Update task (Update, ID:6)

Updating the databases and application modules of Kaspersky Endpoint Security ensures up-to-date protection on your computer. New viruses and other types of malware appear worldwide on a daily basis. The application databases contain information about threats and ways of neutralizing them. To detect threats quickly, you are urged to regularly update the databases and application modules.

A valid application license is required for regular database updates. If there is no active license, you will only be able to perform one update.

The main application update sources are Kaspersky update servers.

Your computer must be connected to the Internet to successfully download the update package from Kaspersky update servers. By default, Internet connection settings are determined automatically. If you use a proxy server, you will need to adjust the connection settings. The update package is downloaded using the Update task.

During an update, the following objects are downloaded and installed on your computer:

• Application databases. During installation, the application downloads the latest databases from one of the Kaspersky HTTP update servers. If the predefined task with default settings (ID=6) is used for updates, the application will update the databases every 60 minutes. You can edit the settings of the predefined task for database and application module updates and create user update tasks.

  If the database update download is interrupted or finishes with an error, the application continues to use the previously installed database version. If application databases were not installed before, the application continues functioning in "without databases" mode. Database and application module updates are still available.

  By default, the application logs the Databases are out of date event (BasesAreOutOfDate) if the last installed database updates were published on the Kaspersky server more than three but less than seven days ago. If the databases have not been updated for seven days, the application logs the Databases are extremely out of date (BasesAreTotallyOutOfDate) event. The database is up-to-date if it was downloaded less than three days ago.

• Application updates. In addition to application databases, you can also update the application itself. Application updates fix vulnerabilities and enhance existing functions.

  The application update can be installed regardless of the state of the application (started or stopped, managed by a Kaspersky Security Center policy) and the update schedule.

  Kaspersky Endpoint Security continues protecting your computer during the application update procedure.

  Kaspersky Endpoint Security transfers the application settings and event log automatically. The settings from the previous application version are exported when the updated version starts.

  If the application does not work properly after the update, it automatically rolls back to the previous version. A message about the application rollback is displayed. It is recommended to contact Kaspersky Technical Support.

During an update, the application and databases on your computer are compared with the up-to-date version at the update source. If your current databases and application modules differ from their respective up-to-date versions, the missing portions of the updates will be installed on your computer.

If the databases are obsolete, the update package may be large, which may cause additional Internet traffic (up to several dozen MB). The amount of the disk space can be up to 3 GB.
